In this paper, an efficient video compression (CR, compression ratio,approximately equals 1000:1) mechanism is presented, and that preserves not only the visual acuity but also the perception fidelity. This is possible because we have made novel utilization of the Human Vision System (HVS). It is well known that our eyes do not pay attention to image pixels rather to intensity changes. Thus the traditional compression based on pixels' dynamic range reduction at all pixel level could be overkill. We furthermore label the discontinuity of the intensity with the derivative jump value across the boundary as the finger print of the edge, and that label together with its actual gray scale value are called the singularity map (SM) that enable us uniquely identify those corresponding control points among neighbor- hood frames without the usual exhaustive search at all image pixels level. The proposed video compression consists of two parallel operations: (1) sending the lossy compression of full image by the HVS wavelets without, however, the block artifact of DCT of JPEG or MPEG, and (2) inserting the original gray scale edge preserved by the SM before the lossy compression operation. Although we know how HVS can extract the SM without the convolution broadening, effectively if we could separate the address from the actual value, we can derive the address by taking into consideration the usual convolution broadening using the Sobel and Canny or any edge operator. Once the address of SM is sharpened without the broadening by inverse diffusion or other tricks, we can straightforwardly look up the actual image value at the gray scale edge from the original image. Since the correspondence among neighborhood frames of the singularity maps is followed in time, we need only send the change of the address without the need of sending the next frame and that fact further compress the redundancy in time from K bytes per frame to K bits on the average. This is the essential principle to enable us to transmit live video via the SINGARS radio at a narrow bandwidth of 16 K bps.
